I have/had over filled the radiator to top, (50/50 anti-freeze up north ) I will leave at 4" lower in radiator so it can expand when stopped and see how that works. The 39 does not have a shroud to direct he air, the fan is just beating air around in the engine compartment. I have my 40 Ford with an electric fan on it and removed the old steel fan and it really changed the cooling of car. 40 also does/did not have a shroud. Told that a product "water wetter" would also improve temp. problem, never used, thanks and will let you know how 12 volt pull through fan preforms in a couple of days/weeks, thank you, BJ
